Re: VRO for 1980 175 Johnson
Dhadley: I have an 82 V6 (J235TLCNE, but badged 175 after complete reman in mid 90s). I premix but it has a oil mixing fuel pump. I know this because I've seen photos and diagrams of the pumps and I recently had to replace a plug/cover that was sealing off the oil intake because it was deteriorating and leaking air.<br /><br />What would it take to convert this engine to VRO? I know I need a tank and some lines, but how about alarms, and other stuff? Is it a straight forward DIY job? How expensive are the parts? I now have both a factory and Seloc manual for this engine.<br /><br />I don't mind premixing that much, but am coming to the school of thought that the risk of messing up premix is greater than an oil injection system failur, especially since I'm hoping my kids will become more independent using the boat.
il mixture to the main bearings directly thru drilled holes in the cylinder half, where the earlier pre-VRO blocks just used recirculated fuel mix with a different plumbing setup.<br /><br />I definitely know how the VRO works (read my old posts), but am explaining the differences in the engine blocks.
